The base of the blend is Papua New Gunea small holder grown coffee (the same as the PNG Gold). This gives creamy almost chocolatey flavours along with a smooth, nice body.
Balancing this, the Colombian Medellin adds in a little acidity and sweetness. The Sumatran Mandheling rounds out the blend with complex flavours,a very full body and a long finish.
Putting it all together you have a blend that is well balanced. Smooth, yet flavourful with good body.
